In the Web3 space, newbies often wonder why WalletConnect is needed when they have a Wallet and DApp. In fact, the answer to this question is closely related to the interoperability, security, and accessibility of the Web3 ecosystem.

Firstly, WalletConnect solves the compatibility issues in the Web3 ecosystem. The early Web3 environment was chaotic, and the connections between different Wallets and DApps often required complex adaptations. For example, MetaMask only supports Ethereum DApps, while using Trust Wallet to navigate Solana applications requires additional setup. Developers had to write multiple sets of code to accommodate various Wallets. The emergence of WalletConnect is like establishing a 'universal language'; whether it's a mobile Wallet or a hardware Wallet, regardless of whether the application is on Ethereum, Polygon, or Solana, as long as this standard is followed, users can connect simply by scanning a code, greatly simplifying the user experience.

Secondly, WalletConnect greatly enhances transaction security. In the cryptocurrency field, the security of private keys is crucial. The advantage of WalletConnect is that it only establishes an encrypted channel between the Wallet and DApp, without touching any sensitive information. Users' private keys are always stored in their own Wallet. For example, when using a Ledger hardware Wallet to connect to Uniswap, the transaction signature is completed entirely within the hardware, making it inaccessible to third parties, which is much safer than entering the key directly on a webpage.

Finally, the ecosystem scale of WalletConnect is impressive. Currently, it supports over 700 wallets and more than 70,000 applications, covering a wide range from cross-chain USDC transfers for individual users to institutional-level applications. This broad support makes WalletConnect an important link connecting various parts of Web3.

Overall, WalletConnect has become an indispensable infrastructure in the Web3 world by addressing compatibility issues, enhancing security, and building a vast ecosystem. It not only simplifies the operational processes for users but also provides developers with more convenient tools, promoting the development and interoperability of the entire Web3 ecosystem. As Web3 technology continues to advance, the importance of WalletConnect may further highlight its role as a key bridge connecting the traditional internet and the decentralized world.
